[Mesa-dev] [PATCH 3/4] st/mesa: pass the clip distance array size to drivers

[Ilia Mirkin]

Patches 1-3 are Reviewed-by: Ilia Mirkin <imirkin at alum.mit.edu> . Not
familiar with the tgsi scan stuff.

Do you have plans on finishing cull distance support btw? Dave Airlie
and Tobias Klaussman have both made attempts at it at one point or
another.
